So about 6 months ago i built my first PC. Today i think something is broken with it or failing.
Today i loaded up BF3. i played for about 2 hours with no problems. after that i hit the end of the round screen and my PC hard locked. Thinking it was a one time deal i restarted and continued as normal. however this time while in BF3 when i whet to my kit customization screen (in game) i had the same hard lock. i rest again, and when i reached the Windows log in screen booth my keyboard and mouse were dead, no lights on both items. unplugging them and plugging them back in to different ports (USB) yielded no results. i then restarted again and my mouse and keyboard worked fine. i let my PC idle for about an hour and came back and it was working, it navigated windows and the web fine logged back into BF3 played a entire match with no problem. got to the end of round screen and hard lock. restarted again, thinking it was my GPU i loaded up the witcher 2 let it idel for about 10 mins and when i returned the computer had hard locked again. updated my video drivers to NVIDIA's latest beta drivers and now the system wont show the ASUS logo or the windows is starting up screen. its just black for about a min until im presented with the windows log in screen. tried poking around in the NVIDIA control panel and my mouse and keyboard died again. What the hell is going on?
